Description

Technical Field

[0001] This utility model relates to the technical field of milling cutter cleaning equipment, and in particular to a PCB milling cutter cleaning device. Background Technology

[0002] PCB milling cutter cleaning devices are essential equipment specifically designed for cleaning PCB milling cutters. They typically consist of a cleaning tank, a cleaning fluid circulation system, a filtration system, and a drying system. When a used PCB milling cutter is placed in the cleaning device, the cleaning fluid, through the circulation system, washes the cutter, effectively removing chips, oil, and other impurities. The filtration system filters out impurities from the cleaning fluid, ensuring its cleanliness and thus improving the cleaning effect.

[0003] Existing technologies, such as the utility model patent with publication number CN210279952U, disclose a PCB milling cutter cleaning device. This patent uses a carrier plate, with a support leg fixedly connected to the lower side of the carrier plate. A quick clamping mechanism is provided on the upper side of the carrier plate. A water pipe runs through the side wall of the carrier plate and is fixedly connected to the carrier plate. A rinsing mechanism is provided at the upper end of the water pipe, and a brushing mechanism is provided on the side wall of the water pipe. This solves the problems of existing PCB milling cutter cleaning devices, such as the inability to quickly clamp and release the milling cutter, which affects the cleaning efficiency, the inability to adjust the angle of the brush, the difficulty in cleaning chips in the chip removal groove, and the existence of cleaning dead corners.

[0004] In the process of cleaning PCB milling cutters using a cleaning device, some existing ultrasonic milling cutter cleaning devices on the market require the user to insert the handle into the device after cleaning to remove the placement frame used to hold the milling cutter. Since water droplets remain on the surface of the cutter inside the placement frame when it is removed, the user needs to place the placement frame back into the device after pulling it out of the water to allow the remaining water droplets to drain. Because the weight of the workpiece placed in the placement frame is relatively heavy, the user's workload increases when the water droplets are drained. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that after the placement frame is pulled out of the water, the user needs to place the placement frame inside the device to allow the residual water droplets to drain. Because the weight of the workpiece placed in the placement frame is relatively heavy, the user's workload will increase when the water droplets are drained. Therefore, a PCB milling cutter cleaning device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a PCB milling cutter cleaning device, comprising a body, a control panel, and support legs. The control panel is mounted on the surface of the body, and the support legs are fixedly connected to the lower surface of the body. A placement frame is placed inside the body, and a lifting assembly is provided on the upper surface of the body.

A collecting wheel is fixedly connected to the surface of both the rotating shaft one and the rotating shaft two. A cable is fixedly connected to the inner wall of the collecting wheel. A connecting sleeve is fixedly connected to the movable end of the cable, and the connecting sleeve is fixedly connected to the gripping part of the placement frame.

[0007] The surface of the second support frame is provided with a drive assembly, which includes a servo motor. The servo motor is fixedly connected to the side surface of the second support frame. The second rotating shaft is bolted to the drive end of the servo motor. The ends of the first and second rotating shafts away from the servo motor are both fixedly connected to sprockets, and chains are installed on the surface of the sprockets.

[0008] Preferably, guide frames are fixedly connected to the side surfaces of both support frame one and support frame two, so that the positions of the guide frames on both sides can be supported and fixed respectively through support frame one and support frame two.

[0009] Preferably, a protective cover is fixedly connected to the side surface of the second support frame. The protective cover can protect the meshing part of the sprocket and the chain to ensure the safety of the chain and sprocket in operation.

[0010] Preferably, the first rotating shaft penetrates the side surface of the first support frame, and the second rotating shaft penetrates the side surface of the second support frame. The second rotating shaft can drive the sprocket on its surface to rotate when the servo motor is working, thereby achieving the driving effect of the sprocket.

[0011] Preferably, the servo motor is electrically connected to the machine body, and the servo motor can drive the rotating shaft two to rotate when powered on, so that the rotating shaft two can drive the storage wheel to rotate.

[0012] Preferably, the guide frame is sleeved with the surface of the cable, and the cable can gradually wrap around the surface of the storage wheel as the storage wheel rotates counterclockwise, thereby pulling the connecting sleeve upward.

[0013] Preferably, the protective cover is fitted onto the surface of the chain, the protective cover is fitted onto the surface of the first rotating shaft, and the protective cover is fitted onto the surface of the second rotating shaft. Through the cooperation of the chain and the sprocket, the first rotating shaft can be rotated while the second rotating shaft is driven by the servo motor.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, by setting up a lifting component and a driving component, the device can automatically lift and place the structure under the user's operation, thereby reducing the problem that the user needs to manually pick up and place the structure when the device is working, which leads to a heavy workload for the user, and further improving the automation level of the device.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a PCB milling cutter cleaning device, including a body 1, a control panel 2 and a support leg 3. The control panel 2 is installed on the surface of the body 1, the support leg 3 is fixedly connected to the lower surface of the body 1, a placement frame 4 is placed inside the body 1, and a lifting component 5 is provided on the upper surface of the body 1.

[0024] In this implementation scheme: the lifting component 5 includes a support frame 1 51, which is fixedly connected to the upper surface of the body 1. A support frame 2 52 is fixedly connected to the upper surface of the body 1. A rotating shaft 1 53 is rotatably connected to the inner wall of the support frame 1 51. A rotating shaft 2 54 is rotatably connected to the inner wall of the support frame 2 52. A storage wheel 55 is fixedly connected to the surface of both the rotating shaft 1 53 and the rotating shaft 2 54. A cable 56 is fixedly connected to the inner wall of the storage wheel 55. A connecting sleeve 57 is fixedly connected to the movable end of the cable 56. The connecting sleeve 57 is fixedly connected to the gripping part of the placement frame 4.

[0025] The surface of the second support frame 52 is provided with a drive assembly 6, which includes a servo motor 61. The servo motor 61 is fixedly connected to the side surface of the second support frame 52. The second rotating shaft 54 ​​is bolted to the drive end of the servo motor 61. The ends of the first rotating shaft 53 and the second rotating shaft 54 ​​away from the servo motor 61 are both fixedly connected with sprockets 62. A chain 63 is installed on the surface of the sprocket 62.

[0026] Specifically, guide frames 58 are fixedly connected to the side surfaces of support frame 1 51 and support frame 2 52. The positions of the guide frames 58 on both sides can be supported and fixed by support frame 1 51 and support frame 2 52 respectively.

[0027] Specifically, a protective cover 64 is fixedly connected to the side surface of support frame 2 52.

[0028] In this embodiment, the protective cover 64 can protect the meshing part of the sprocket 62 and the chain 63 to ensure the safety of the chain 63 and the sprocket 62 in operation.

[0029] Specifically, the first rotating shaft 53 penetrates the side surface of the first support frame 51, and the second rotating shaft 54 ​​penetrates the side surface of the second support frame 52. When the servo motor 61 is working, the second rotating shaft 54 ​​can drive the sprocket 62 on its surface to rotate, thereby achieving the driving effect of the sprocket 62.

[0030] In this embodiment, the servo motor 61 is electrically connected to the body 1.

[0031] In this embodiment: the servo motor 61 can drive the rotating shaft 54 ​​to rotate when it is powered on, so that the rotating shaft 54 ​​can drive the storage wheel 55 to rotate.

[0032] Specifically, the guide frame 58 is sleeved with the surface of the cable 56. As the cable 56 rotates counterclockwise, it gradually wraps around the surface of the receiving wheel 55, thereby pulling the connecting sleeve 57 upward.

[0033] Specifically, the protective cover 64 is fitted onto the surface of the chain 63, the protective cover 64 is fitted onto the surface of the first rotating shaft 53, and the protective cover 64 is fitted onto the surface of the second rotating shaft 54.

[0034] In this embodiment: through the cooperation of chain 63 and sprocket 62, rotating shaft 53 can be driven to rotate during the process of servo motor 61 driving rotating shaft 2 54.

[0035] Working principle: When cleaning the milling cutter, place the milling cutter into the placement frame 4. After placement, lower the placement frame 4 into the machine body 1. Once the placement frame 4 is in the machine body 1, operate the control panel 2. The control panel 2 controls the machine body 1 to work. The machine body 1 is powered on and vibrates to generate ultrasonic waves, which, together with its internal water source, clean the milling cutter in the placement frame 4. After cleaning, turn on the servo motor 61. The servo motor 61 drives the second rotating shaft 54. The second rotating shaft 54, in conjunction with the sprocket 62 on its surface, drives the chain 63. The chain 63 meshes with the sprocket 62 on the surface of the first rotating shaft 53. Under the action of the chain 63, the sprocket 62 on the surface of the first rotating shaft 53 rotates the first rotating shaft 53. When the first rotating shaft 53 and the second rotating shaft 54 ​​rotate counterclockwise synchronously, the receiving wheel 55 is driven to rotate counterclockwise. During the rotation of the receiving wheel 55, the cable 56, guided by the guide frame 58, gradually winds into the receiving wheel 55. During the winding process, the rope 56 pulls the connecting sleeve 57 upward, which in turn pulls the placement frame 4 upward. As the placement frame 4 moves, it lifts the milling cutter out of the water. Once the milling cutter is out of the water, the servo motor 61 is turned off, and the servo motor 61 stops working. At the same time, the placement frame 4 stops moving, and the water on the surface of the milling cutter can be drained inside the machine body 1. After the water has drained, the servo motor 61 is turned on again, and it continues to lift the placement frame 4 according to the above steps. When the placement frame 4 is raised to its maximum height, the servo motor 61 is turned off, and the placement frame 4 stops moving. Then, the milling cutter can be removed from the placement frame 4. By setting up the lifting component 5 and the drive component 6, the equipment can automatically lift the placement structure under the user's operation, thereby reducing the problem that the user needs to manually pick up the placement structure during equipment operation, which leads to a heavy workload for the user, and further improving the automation level of the equipment.
